Check Digit Verification of cas no
The CAS Registry Mumber 36519-42-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,6,5,1 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 36519-42:
(7*3)+(6*6)+(5*5)+(4*1)+(3*9)+(2*4)+(1*2)=123
123 % 10 = 3
So 36519-42-3 is a valid CAS Registry Number.
